What You Lend Is Lost; When You Ask For It Back, You May Find A Friend Made An Enemy By Your Kindness. If You Begin To Press Him Further, You Have The Choice Of Two Things - Either To Lose Your Loan Or Lose Your Friend.

To Snatch The Worm From The Trap.

Ones Oldest Friend Is The Best.

Where There Are Sheep, The Wolves Are Never Very Far Away.

What Is Thine Is Mine, And All Mine Is Thine. [lat., Quod Tuum'st Meum'st; Omne Meum Est Autem Tuum.]
